What is Silver Ion Antimicrobial Technology?

Everyday we are surrounded by microorganisms including bacteria. Practically everything humans or animals touch – kitchen counters, bathroom fixtures, doorknobs, floors or medical equipment – can potentially be harboring bacteria like Escherichia coli and Staphylococcus aureus, which can cause severe illness once in contact with the human body.

Established criteria says that to be safe for humans, microbial flora on high-touch surfaces such as hospital beds must not exceed 100 colony-forming units (CFU)/100cm2 potential pathogens and 250 CFU/100cm2 total microbial colony counts. U.S. Army researchers found that harsh disinfectants must be used every two hours to keep ICU bed rails below those levels of disease-causing bacteria, including MRSA and VRE, two antibiotic-resistant strains of bacteria. The researchers’ primary conclusion: Hospital-approved disinfectants can quickly reduce bacteria counts to safe levels, but the bacteria rebound quickly above 250 CFU/100cm2, and each bed rail must be re-disinfected every 120 minutes to maintain continuous, safe protection.

Even with the promise of continuous disinfection, it is not reasonable to all surfaces around us to be cleaned every two hours. The ability to provide continual microbial reduction can be accomplished using antimicrobial silver.

Silver ion antimicrobial technology is a silver-based active ingredient that can be incorporated into polymers, coatings, textiles and more to offer continuous product protection against bacteria.

Silver has long been used as an antimicrobial agent, at least since Hippocrates first described silver’s antimicrobial properties in 400 B.C., but it wasn’t until 1972 that scientists understood how silver works. Small amounts of silver disrupt bacteria’s metabolism by preventing it from converting nutrients into energy, which inhibits bacteria survival, reproduction and colonization.

Microban Silver Ion Antimicrobial Technologies

Microban® silver ion antimicrobial technologies are largely based on silver phosphate glass active ingredients. Each technology is registered for use in both the US (EPA) and the EU (BPR) and is safe to use in a variety of applications including those that come in contact with food. Their small, uniquely shaped particles are designed to release silver ions faster than other silver ion antimicrobial technologies. Even though the particles are small, they are still too large to be considered a nanotechnology.

Typical applications for Microban® silver technology include bed rails, light switches, powder coated door handles, food storage containers, water tanks, and textile based materials such as bedding and gowns.

The Benefits of Silver Ion Antimicrobial Technology

Our innovative SilverShield® Series takes the proven antimicrobial effectiveness of silver a huge step forward. Because of its unique geometry and highly efficient release mechanism, SilverShield® reacts 8 times faster than other antimicrobial silver while maintaining durability and integrity in substrates like polymer.

  • Provides up to 99.9% reduction of Salmonella enterica, E. coli, MRSA and VRE in 2 hours at room temperature, vs. up to 24 hours for competitor products
  • The Silver ion active ingredient in SilverShield® is constantly presented on the surface of a treated product, ready to be released 24/7
  • Complements and helps to extend the effectiveness of standard chemical disinfecting routines used in medical settings, homes and public spaces
  • Remains effective even if a treated object is nicked or scratched
  • Stays inert until it comes into contact with damp environments, when it releases the antimicrobial silver – just enough to inhibit the bacteria’s metabolism and prevent reproduction
  • The accuracy of SilverShield® makes it a weapon in the ongoing battle against harmful microbes

Microban® silver technology is suitable for materials such as polymers, coatings, ceramics, and more. Integration is simple and seamless and does not disrupt existing manufacturing processes. Our engineers develop and test customized formulations of antimicrobial silver for each individual product. These custom formulations are tested with your own materials both for antimicrobial effectiveness and to ensure that our silver technology will not degrade or decrease the aesthetics or function of any part of your product.

Microban® will work with you to ensure that the solution we deliver fits the desired antimicrobial performance criteria through our state-of-the-art microbiological and analytical chemistry test facilities, and regulatory laws in your particular country. In addition, our global network of technical specialists is available to address processing issues if they arise, while our customer service specialists are experienced in export/import, shipping and customers clearance to ensure timely delivery of our antimicrobial products to the manufacturing site of your choice.
